'11 GSR better baseline vs '08 GSR
Hi guys,
I’m looking at some dyno runs on stock EVO X posted here, claiming that 2011 GSR has a much better baseline compared to 2008 GSR.
But if I look at the 2 ROMs (let’s consider last stocks for both, i.e. 52680024 for ’08 and 56890010 for ‘11), I cannot see any significant difference:
- the solenoids WGDC maps are exactly equal
- in WOT area, the AFR is the same or even richer in '11
- in WOT area, the ignition timing is the same (some differences in cruising area)
- just MIVEC intake table is a bit more different, but I think the difference in WOT area is not big enough to explain a gain of around 15-20 whp!
And in any case, the Target Engine Load is the same...!
So, where does this additional power come from??
Thanks for your opinions.
Bye

I agree, for sure if you tune them you'll get the same results.
But what I cannot understand is where these 2 stock roms are different, they seem pratically identical in all the tables!

Airflow and AFR affects power
There are other maps that are also different
ive never seen a 52680024 baseline but im willing to bet its close to 2011
Ill be testing this theory soon :-D
